We currently have a SharePoint list which updates every weekend using a flow which pulls the values from an Excel File. This file is updated externally, with the flow deleting the existing contents of the list and recreating it from the Excel file.
I'm trying to create another list which contains the new values which were added to the Excel file in the last update. I've tried cross-referencing the Excel values with the original list before it updates and pushing those which aren't there onto the new list but I've not had any luck creating this flow. Is there a better way to go about this?
